ADVERTISING OR DISPLAY DEVICE.

SPECIFICATION forming part of Letters Patent No. 400,549,6lated April 2,1889.

' Application led August 24,1888. Serial No. 283,669. (No model.) I

To all whom it may concern: Y

Be it known that I, ANDREW DAHLsTRoM,

residing at Ashton, in the county of OsceolaV and State of Michigan,have invented new` and useful Improvements in an Advertising or DisplayDevice, of which the following is a specification.

My invention has for its object the con'- struction of a device whichmay be used in various placessuch as railroad-stations, hotel-lobbies,dac., but is more especially adapted for use in diningerooms of hotelsand dwellings-and which is arranged to automatically revolve and displaydilerent advertisements, bills of fare, scripture-texts, or any otherob'- ject which is desired to be presented to view. My inventionconsists in a cylindrical body provided with a series of openings in itssides, and a tape or ribbon upon which is printed, painted, or otherwiseproduced the various advertisements, texts, or other objects to bepresented, and these objectsv are so placed upon the ribbon as to alwaysbein alignment with one of thev various openings when said ribbon isrevolved. The ribbon is retained in said circular body and arrangedtherein v upon rollersone at each of the ribbonsvone of which rollers isadapted to unwind while the opposite roller will wind up the ribbon.

Suitable gearing devices are employed to operate the rollers and thebody; and the invention further consists in the peculiar combination andthe novel construction of parts, as will be hereinafter -fully describedin the specification, and particularly pointed out in the claims.

As my inyention is more especially intended to be used in connectionwith self-waiting tables, I shall describe the same in connection with atable, reference being had to the accompanying drawings, in which-Figure l is a vertical section of my device, showing the same inconnection with a por! tion of` a table. Fig. 2 is a pian view of thedevice with the top casing removed. Figs. 3, 4, andv 5 are horizontalsectional views on the lines 3 3, 4 4, and 5 5, Fig. l. Fig. 6 is anenlarged sectional viewof the central core and roller, and Figs. 7 and 8are detail views hereinafter referred to.

In the practical application of my improvement I provide a centralopening, a., in the table A or other framing to which the same may beattached, and a suitable metallic frame, B B', is provided to supportthe lower portions of the device. Projecting downwardly from thetable-top is a hollow shaft, C, the lower end of which rests upon thelower bar, B, of the frame B. Disposed to one side of the shaft Cbeneath the table and journaled in the frame B is the drum-shaft D, uponwhich is mounted and has one end secured thereto the power-spring E, theopposite end .of said spring` being` attached to the frame B.

This shaft is provided with the usual pawland-ratchet device, d', andhas secured upon its lower projecting end, d2, a handle, d3, by means ofwhich the spring E may be wound up when so desired.

d4 is the drive-gear operated by said spring E, which meshes with apinion, e, mounted upon the lower end of the central shaft, O, by imeans of which motion is imparted thereto.

Uis a plate disposed upon the lower plate of the frame B, beneath thespring E, and is provided with a slot encompassing the drumshaft andprovided with a projecting nger, u, adapted to engage with a notchedhub, c. The opposite end of the plate U is provided with a rod-likeprojection, u2, which projects through the side ofY the table-frame andis provided with a handle, ug. By this arrangement it will be seen thatwhen the plate Uis pulled backward the nger will be released from thehub e. and the central shaft permitted to turn and thereby operate thedisplay devices; but when the plate U is normally pushed forward bymeans of a spring, a, the projecting finger will enter the notched hub eand prevent the same from turning. The 'upper end of the shaft C extendsto a distance about in line with the top of the table, said end beingsquare in cross-section.

30 denotes the display device, which consists of the base 3l, thetubular column 32, the enlarged circular casing 33, and the top 34.

35 denotes a tubular shaft having a hollow head square in cross-sectionat its top and extending downwardly through the column 32,"and having asquared lower end.

36 denotes a coupling-piece, its opposite ends being square incross-section, and which IOO connects the shaft and the hollow shaft C,as shown. rlhus it will be seen that the same 'motion applied to thehollow shaft C is imparted to the shaft 55.

The circular casing 33 is formed of the baseplate 38, and the circularvertical portion 39. The portion 39 is provided with a series ofopenings, 40, through which the picture, bill of fare, scriptural text,the., may be readily seen. A glass rim, 4l, is placed inside the opening40, as shown.

In connection with this display-case it is desired to arrange theadvertisement or picture on a continuous tape or ribbon, which ribbon isto have its objective parts so arranged that each pull upon the plate Uwill permit the turning of the ribbon one spacethat is, to change fromone opening to the other. To this end I arrange a central core, 42, anintermediate spool,43, and a series of rollers, 44, arranged in a circlenear the outer rim of the case 33, and fasten one end of the ribbon tothe spool 43, pass it around the rollers 44, between them and the glassrim, and pass it from them to the core 42, to which the opposite end issecured in a manner as will be presently described.

The spool 43 is provided with a key-seat, by means of which a key may beapplied, and the main bodyof the ribbon thereby be wound thereon.

For revolving the display-ribbon, I provide a hollow core, 42, (see Fig.6,) with a projecting hub, 4G, which is square in cross-section, andwhich hub lits into the squared end of the tubularshaft 35. Itismanifest that each partial turn of the shaft 35 will revolve the core42, and thereby unwind a portion of the ribi bon from the spool 43 andwind it upon itself.

As previously mentioned, the objective parts of the ribbon are soarranged that each movement of the gearing devices will turn the ribbonone space. New, as the objects on the ribbons are each properly spacedin relation to the ixed openings in the sides of the casing, it ismanifest that if the core 42 were made of a solid body the ribbon inwinding thereon would increase the diameter of the core at each turn,which would soon throw the objective parts of the ribbon out of truealignment with the openings, and thereby prevent a clear representationthereof. To overcome this objection, I have provided a contractile core,which will automatically always present the same diameter, whether theribbon be at its first turn upon it or entirely wound upon the same. Tothis end I form the core 42 with a top plate, 4S, and bottom plate, 49,and the four (more or less) segmental sections, 50. rlhese sections areeach provided with a central slot, 51, which embraces a verticalstoprod, 52, which limits the outward motion of said sections.

To conveniently secure one end of the ribbon to the core, I provide arecess, 70, in one of the sections, and a rod, 7l, arranged to passthrough the upper and lower plates, 4S and 49,

which is sealed in the recess 70, as shown in the drawings. rlhe bodyportion of said rod 7l is of a cam shape in cross-section. (See Fig. 7.)

In securing the ribbon, one end thereof is placed in the recess. The rod7l is then passed through the top plate, through the recess, and withits cam portion 8O placed outward and its lower end entered into thebottom plate. It (the rod) is then given a half-turn, which causes thecam portion to bear against the ribbons or tape, and thereby securelyfasten the same to the core42. The interior faces of the sections 50form a conical opening, 54, into which tits a hollow screw-plug, 55,having a conical-shaped upper portion which fits within the conicalopening 54 and holds said sections 50 in proper concentric alignment.The lower end of said screw-plug is screwed into a threaded portion ofthe shaft 35, and is provided at its upper end with a suitable handhold,59, for screwing the same into position.

In the cap-plate 30 of the display device I form a vertical socket, G0,adapted to receive the end of the screw-plug. The screw-plug having beenplaced in position, the cap-plate put in place, and the tubular shaft 35caused to operate, the same will cause the screw-plug (which is heldfrom turning by means of the cap-plate) to graduallyrise up, and eachmovement of the tubular shaft 35 (which acts as a nut upon the screwportion of the plug) will cause the screw-plug to rise, say, one thread,which will decrease the diameter of the body of the contractile core aproportionate degree; but the addition of the ribbon thereupon will keepthe entire diameter of the core and ribbon combined always the same,this operation being repeated until the ribbon is all unwound from thespool 43, at which time the screwplug will have risen to its highestpoint into the recess in the cap-plate and the main diameter of the bodyof the core 42 reduced to its minimum. The cap-plate is then removed,the ribbon again wound upon thespool 43, the plug again screwed intoposition, the cap replaced, and the same is again ready for operation.

It will be understood that the hub e (see Fig. 8) being provided withnotches e2 e2 diametrically opposite, when the finger is released fromone notch t-he shaft will give a half-turn, and the relation between theribbon mechanism and the shaft is such that a one-half turn of the shaftwill give the ribbon a turn equal to one space in the sides of thecasing.

62 denotes the rod, which passes centrally through the several hollowshafts, and has its lower end screwed into the frame, and has at itsupper end a circular nut, G3.

Frein the foregoing description, taken in connection with the drawings,the operation and advantages of my improvement will be readilyunderstood.

Having thus described myinvention, what I claim, and desire to secure byLet-ters latent, 1s-
